Underwater Acoustics For Biologists and Conservation Managers Training
Underwater Acoustics For Biologists and Conservation Managers Training Course Description
This three-day Underwater Acoustics For Biologists and Conservation Managers Training is designed for biologists, and conservation managers, who wish to enhance their understanding of the underlying principles of underwater and engineering acoustics needed to evaluate the impact of anthropogenic noise on marine life. This course provides a framework for making objective assessments of the impact of various types of sound sources. Critical topics are introduced through clear and readily understandable heuristic models and graphics.
• The fundamentals of sound and how to properly describe its characteristics
• Modern acoustic analysis techniques
• What are the key characteristics of man-made sound sources and usage of correct metrics
• How to evaluate the resultant sound field from impulsive, coherent and continuous sources
• What animal characteristics are important for assessing both impact and requirements for monitoring/and mitigation
• Capabilities of passive and active monitoring and mitigation systems
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
The Language of Physics and the Study of Motion This quick review of physics basics is designed to introduce acoustics to the neophyte.
What Is Sound and How To Measure Its Level This includes a quick review of physics basics is designed to introduce acoustics to the neophyte. The properties of sound are described, including the challenging task of properly measuring and reporting its level.
Digital Representation of Sound Today, almost all sound is recorded and analyzed digitally. This section focuses on the process by which analog sound is digitized, stored and analyzed.
Spectral Analysis: A Qualitative Introduction The fundamental process for analyzing sound is spectral analysis. This section will introduce spectral analysis and illustrate its application in creating frequency spectra and spectrograms.
Basics of Underwater Propagation and Use of Acoustic Propagation Models The fundamental principles of geometric spreading, refraction, boundary effects and absorption will be introduced and illustrated using propagation models. Ocean acidification
Question and Answer Session
The Acoustic Environment and its Inhabitants
The ambient Acoustic Environment The first topic will be a discussion of the sources and characteristics of natural ambient noise.
Basic characteristics of anthropogenic sound sources – implosive (airguns, pile drivers, explosives). Coherent (sonars, acoustic models, depth sounder, profilers,) continuous (shipping, offshore industrial activities).
Review of Hearing Anatomy and Physiology: Marine Mammals, Fish and Turtles – review of hearing in marine mammals.
Marine Wildlife of interest and their characteristics – MM, turtles fish, inverts. Bioacoustics, hearing threshold, vocalization behavior; supporting databases on seasonal density and movement.
Question and Answer Session
Effects of Sound on Animals
Review and History of ocean anthropogenic noise issue – current state of knowledge and key references.
Assessment of the impact of anthropogenic sound – Source-TL- receiver approach, level of sound as received by wildlife, injury, behavioral response, TTS, PTS, masking, modeling techniques, field measurements, assessment methods.
Monitoring and mitigation techniques – passive devise (fixed and towed systems). Active Detections, matching device capabilities to environmental requirements 9examples of passive and active
localization, long-term monitoring, fish exposure testing).
